Swiss sizing uses pit-to-pit measurements in centimeters to denote sizes. To find your pit-to-pit size, take a well-fitting shirt and lay it flat on the ground. Measure it from armpit to armpit. This number is your pit-to-pit size measurement. For example, a medium (48) measures 19" from pit to pit. A large (52) measures 20.5" from pit to pit. An extra large (56) measures 22" from pit to pit.
